DISPLAY DEVICE, APPARATUS FOR COMPENSATING DEGRADATION AND METHOD TEHEROF

摘要

A display device includes pixels, a deterioration compensation part which calculates reference use time when the real deterioration rate of the pixels is changed into a reference deterioration rate on a reference deterioration curve by using a material weighted value on a reference material, a brightness weighted value on reference brightness, and a temperature weighted value on reference temperature and generating a control variable according to the reference use time, and a power supply part which controls the voltage difference of a first power voltage and a second power voltage which provide a driving current to the pixels according to the control variable.
